Context

In coding interviews, interviewers evaluate not only whether you reach the correct solution, but also how clearly you reason through the problem. A strong explanation shows structure, trade-off awareness, and the ability to adapt under pressure.

Core Question

Explain your problem-solving approach for a LeetCode-style interview question. In your answer, address:

1. How you clarify the problem and identify constraints before coding.
2. How you move from a brute-force idea to an optimized solution.
3. How you communicate complexity, edge cases, and testing while coding.

Scope Guidance

The interviewer expects a practical framework you can apply across common algorithm problems involving arrays, strings, hash tables, and pointer-based techniques. Focus on process, decision-making, and communication rather than deep implementation details for one specific problem.
